Interplay of the two ancient metabolites auxin and MEcPP regulates adaptive growth. [PDF]

open access: yes, 2018
The ancient morphoregulatory hormone auxin dynamically realigns dedicated cellular processes that shape plant growth under prevailing environmental conditions. However, the nature of the stress-responsive signal altering auxin homeostasis remains elusive.

phot1 inhibition of ABCB19 primes lateral auxin fluxes in the shoot apex required for phototropism [PDF]

open access: yes, 2011
It is well accepted that lateral redistribution of the phytohormone auxin underlies the bending of plant organs towards light. In monocots, photoreception occurs at the shoot tip above the region of differential growth.

Temporal and spatial auxin responsive networks in maize primary roots

open access: yesQuantitative Plant Biology, 2022
Auxin is a key regulator of root morphogenesis across angiosperms. To better understand auxin-regulated networks underlying maize root development, we have characterized auxin-responsive transcription across two time points (30 and 120 min) and four ...

Auxin Biosynthesis [PDF]

open access: yesThe Arabidopsis Book, 2014
lndole-3-acetic acid (IAA), the most important natural auxin in plants, is mainly synthesized from the amino acid tryptophan (Trp). Recent genetic and biochemical studies in Arabidopsis have unambiguously established the first complete Trp-dependent auxin biosynthesis pathway.

Auxin‐activated MdARF5 induces the expression of ethylene biosynthetic genes to initiate apple fruit ripening

open access: yesNew Phytologist, 2020
Summary The gaseous plant hormone ethylene induces the ripening of climacteric fruit, including apple (Malus domestica). Another phytohormone, auxin, is known to promote ethylene production in many horticultural crops, but the regulatory mechanism ...

The cyclophilin A DIAGEOTROPICA gene affects auxin transport in both root and shoot to control lateral root formation [PDF]

open access: yes, 2015
Cyclophilin A is a conserved peptidyl-prolyl cis-trans isomerase (PPIase) best known as the cellular receptor of the immunosuppressant cyclosporine A. Despite significant effort, evidence of developmental functions of cyclophilin A in non-plant systems ...

Up in the air: Untethered Factors of Auxin Response [version 1; referees: 5 approved]

open access: yesF1000Research, 2016
As a prominent regulator of plant growth and development, the hormone auxin plays an essential role in controlling cell division and expansion. Auxin-responsive gene transcription is mediated through the TRANSPORT INHIBITOR RESPONSE1/AUXIN SIGNALING F ...

Auxin Response Factors: output control in auxin biology [PDF]

open access: yesJournal of Experimental Botany, 2017
AbstractThe phytohormone auxin is involved in almost all developmental processes in land plants. Most, if not all, of these processes are mediated by changes in gene expression. Auxin acts on gene expression through a short nuclear pathway that converges upon the activation of a family of DNA-binding transcription factors. These AUXIN RESPONSE FACTORS (

The PIN-FORMED (PIN) protein family of auxin transporters [PDF]

open access: yes, 2009
The PIN-FORMED (PIN) proteins are secondary transporters acting in the efflux of the plant signal molecule auxin from cells. They are asymmetrically localized within cells and their polarity determines the directionality of intercellular auxin flow.
